Duchenne muscular dystrophy is an X-Linked neuromuscular disorder, and the most common muscular dystrophy. Neuropsychiatric phenotype associated to DMD gene mutations include now low IQ scores, epilepsy, autism, and attention deficit disorder. These have been observed with higher frequency in mutations that disrupt the short isoforms Dp71 and Dp140. West syndrome has been previously reported in two unrelated patients with Duchenne muscular dystrophy. Here, we report the third patient with West syndrome who had a novel hemizygous nonsense pathogenic variant in the exon 8 of the DMD gene c.811C&gt;T, p.(Gln271*), suggesting West syndrome as part of the neuropsychiatric spectrum in Duchenne muscular dystrophy.We evaluated the clinical histories, motor and pulmonary functions, cardiac phenotypes and GAA genotypes of an Indian cohort of twenty patients with late onset Pompe disease (LOPD) in this multi-centre study. A mean age at onset of symptoms and diagnosis of 9.9?±?9.7 years and 15.8?±?12.1 years respectively was identified. All patients had lower extremity limb-girdle muscle weakness. Seven required ventilatory support and seven used mobility assists. Of the four who used both assists, two received ventilatory support prior to wheelchair use. Cardiac involvement was seen in eight patients with various combinations of left ventricular hypertrophy, tricuspid regurgitation, cardiomyopathy, dilated ventricles with biventricular dysfunction and aortic regurgitation. Amongst 20 biochemically diagnosed patients (low residual GAA enzyme activity) GAA genotypes of 19 patients identified homozygous variants in eight and compound heterozygous in 11 27 missense, 3 nonsense, 2 initiator codon, 3 splice site and one deletion. Nine variants in 7 patients were novel. The leaky Caucasian, splice site LOPD variant, c.-32-13T&gt;G mutation was absent. https://www.selleckchem.com/products/danirixin.html This first study from India provides an insight into a more severe LOPD phenotype with earlier disease onset at 9.9 years compared to 33.3 years in Caucasian patients, and cardiac involvement more than previously reported. The need for improvement in awareness and diagnosis of LOPD in India is highlighted.The ability of radiotherapy to enhance antigenicity and adjuvanticity of an irradiated tumor has stimulated the interest for its combination with immuno-oncology agents. However, radiotherapy often generates multiple layers of host responses which likely depends on the tumor biology, the immune cell infiltration and the induction of immunosuppressive signals post radiotherapy. Consequently, translation of preclinical findings to the clinic is more convoluted than anticipated which underscore the need to decipher molecular and cellular mechanisms elicited by radiotherapy. Here we review pro-inflammatory and immunosuppressive mechanisms triggered by radiotherapy that impact the outcome of antigen specific T cell killing and discuss how radiation-induced immunostimulatory mechanisms can be exploited to reactivate the host's immune system, especially in the context of immunotherapy.The anode heel effect can be used to optimize image quality and/or patient dose in digital radiography (DR). In film-screen radiography, the effect can equalize optical density in regions of varying attenuation. Clinical experience suggests that the implementation of DR has led to less awareness of anode orientation. Post-processing is assumed to compensate, but may also alter image impression and potentially obscure image details. Published evidence was examined for the influence of the anode heel effect on image quality in DR.
A systematic literature search was carried out using PubMed, Embase, and Web of Science databases. Title and abstracts were screened blinded by three authors, according to in-/exclusion criteria, followed by full-text analysis for final inclusion. Studies where technical and/or visual image quality were reported, was included. All studies were analyzed and assigned quality scores, according to relevant questions. The authors devised a scoring system based on reported information pno firm recommendations for anode orientation relating to image quality in DR can be provided.Results from a single-institution study support the need of a dose constraint for patients who have previously undergone hip replacement surgery. Our study provides evidence that a dose above 30 Gy to the area of hip prosthesis is significantly correlated with later hip arthroplasty dysfunction as measured by the Harris Hip Score. As total hip arthroplasty becomes more and more common, it is urgent to further look into radiation therapy treatment parameters that can be modified to improve the quality of life of patients who receive pelvic irradiation after hip arthroplasty. Further prospective studies are needed to extract safe conclusions.Insufficient sleep duration is common among children and adolescents worldwide, and the decline of sleep duration during the recent years is troubling. This study aimed to learn the status of insufficient sleep duration and to explore its influencing factors among children and adolescents in Zhejiang Province, China.
A stratified sampling technique was employed in the present cross-sectional study. Demographic characteristics, sports time as well as sedentary behavior were investigated.
A greater proportion of children than adolescents reported insufficient sleep duration (36.4% versus 19.2%, p=0.001). For children, insufficient sleep duration was associated with age (OR=1.290, 95%CI 1.069-1.557), watching movies or TV shows with smartphones after school (OR=3.098, 95%CI 1.293-7.420), surf the internet after school (OR=0.113, 95%CI 0.013-0.969), walk to school (OR=0.289, 95%CI 0.105-0.793). For adolescents, insufficient sleep duration was associated with watch TV after school (OR=0.379, 95%CI 0.148-0.970), watching movies or TV shows with smartphones after school (OR=4.744, 95%CI 1.799-12.507), do homework after school (OR=0.265, 95%CI 0.086-0.813).
An unhealthy sedentary screen lifestyle profile may have influence on insufficient sleep duration. Urgent actions are needed to improve sleep duration among children and adolescents.
